Damian Guy created KAFKA-5787: --------------------------------- Summary: StoreChangeLogReader needs to restore partitions that were added post initialization Key: KAFKA-5787 URL: https://issues.apache.org/jira/browse/KAFKA-5787 Project: Kafka Issue Type: Bug Components: streams Affects Versions: 0.11.0.1, 1.0.0 Reporter: Damian Guy Assignee: Damian Guy Priority: Blocker
Investigation of {{KStreamRepartitionJoinTest}} failures uncovered this bug. If a task fails during initialization due to a {{LockException}}, its changelog partitions are not immediately added to the {{StoreChangelogReader}} as the thread doesn't hold the lock. However {{StoreChangelogReader#restore}} will be called and it sets the initialized flag. On a subsequent successfull call to initialize the new tasks the partitions are added to the {{StoreChangelogReader}}, however as it is already initialized these new partitions will never be restored. So the task will remain in a non-running state forever -- This message was sent by Atlassian JIRA (v6.4.14#64029)
